ESA and Thales Alenia Space have signed a contract to develop the new high-priority Copernicus Radar Observation System for Europe in L-band (ROSE-L) environmental monitoring mission - as part of Europe's Copernicus programme. The contract was signed in the presence of Riccardo Fraccaro, Undersecretary of the Italian Prime Minister's Office, and ESA's Director General, Jan Worner.

With launch planned in 2028, ROSE-L will provide continuous day-and-night all-weather monitoring of Earth's land, oceans and ice, and offer frequent images at a high spatial resolution.

During its 7.5-year lifetime, the ROSE-L mission will realise new information that cannot be gathered by existing satellites or through other means. ROSE-L will deliver essential information on forests and land cover, leading to improved monitoring of the terrestrial carbon cycle and carbon accounting.

The mission will also greatly extend our ability to monitor minute surface displacements and helping detect geohazards. It will automatically map surface soil moisture conditions and monitor sea and land ice, greatly helping climate change research and mitigation.

From its 690 km polar orbit, ROSE-L will carry an active phased array synthetic aperture radar instrument. The radar antenna will be the largest planar antenna ever built measuring an impressive 11 metres by 3.6 metres - roughly the size of 10 ping-pong tables.

With a contract secured worth euro 482 million, Thales Alenia Space in Italy is the prime contractor for the mission, with Airbus Defence and Space in Germany responsible for the radar instrument. The industrial team includes 29 companies (including 15 SME's) from 15 countries.

ESA's Director of Earth Observation Programmes, Josef Aschbacher, said, "I am extremely glad to sign the ROSE-L contract. ROSE-L will not only complement the radar capabilities of the current Copernicus Sentinel-1 mission, but will also provide a new set of measurements of vegetation, ice and ocean parameters. It will be a key satellite mission to better understand climate change and simulate its impact on humankind."

The European Commission's Director-General for Defence Industry and Space, Timo Pesonen, commented, "We are happy to see the signature of the ROSE-L contract. Its features are expected to respond to several needs we have identified in particular in land management and in ocean monitoring. We look forward to welcoming ROSE-L in the Copernicus Constellation."

The contract for ROSE-L is the last of the six new high-priority candidate missions to be signed. The six Copernicus high-priority Sentinel Expansion missions are planned to complement the current capabilities of the Sentinels and address EU policy priorities and gaps in Copernicus user needs.

The European Copernicus flagship programme provides Earth observation and in situ data, as well as a broad range of services for environmental monitoring and protection, climate monitoring and natural disaster assessment to improve the quality of life of European citizens.

Copernicus is the biggest provider of Earth observation data in the world - and while the EU is at the helm of this environmental monitoring programme, ESA develops, builds and launches the dedicated satellites. It also operates some of the missions and ensures the availability of data from third party missions.

Copernicus satellites keep eyes on icebergs for Vendee Globe
Paris (ESA) Dec 03, 2020
On 8 November, 33 intrepid sailors set off from Les Sables-D'Olonne in western France to take part in the most extreme, solo, non-stop, race around the world: the Vendee Globe. The route of around 45 000 km takes them down through the Atlantic and into the heart of the Southern Ocean - which is where they are heading now. Thanks to information from satellites, an ice exclusion zone has been established to help keep sailors away from icebergs. For extra safety, satellite images and data are being used to ... read more
